I followed the typical tutorial on installing MATE over ubuntu with apt-get. After a successful install, the icons of files and folders go blank, and the menu icons as well.
The best answer I could get from MATE forums is to modify startup scripts so mate-settings-daemon isn't run as a daemon. But that is a band-aid solution, and doesnt address the problem.
I looked into the same file on Mint, and sure enough, your distro runs it as a daemon. So I'd like to know how you got it to work, since Mint comes from Ubuntu, and I am basically repeating the process with Precise and MATE. Somebody here must know why it dies, and what is needed to get it to run properly.
